We will consider some inequalities on operator means for more than three operators, for instance, ALM and BMP geometric means will be considered. Moreover, log-Euclidean and logarithmic means for several operators will be treated.
This work is based on research supported by the INOUE ENRYO Memorial Foundation for Promoting Sciences.
